St. Asteria is the patron of Bergamo in Lombardy in Italy. She was the sister of St. Grata of Bergamo where, during the time of the persecutions under Emperors Diocletian and Maximian, they both were responsible for burying the body of St. Alexander.

St. Grata was put to death for her deed, with Asteria also being responsible for the burial of her remains.

In 307, shortly after her sister’s martyrdom, St. Asteria was arrested, tortured and beheaded.
